Best Desktop for TS4

@BabiGrim  The configuration is great for what you want to do now.  The reason I didn't add a stronger graphics card is that I'm not sure anything, other than maybe the $1,200 Nvidia 2080 ti, will run the future editions of GTA and Dragon Age well on ultra graphics settings.  You could still play on slightly lower settings, of course, but if your goal is peak performance, it would be better to get a good-enough card now and get a newer, more powerful one in two or three years.  You wouldn't have to install it yourself, either: if you don't know anyone who could help, you could have it done at a store.

Still, if you'd like to spend the money now, the next graphics card up is an extra $148, and the one after that is $278 more than the original.  (There are a number of slightly different models of cards in each category, because they're made by several different companies, but those two are the cheapest good options.)  Again, I wouldn't count on either of these cards running future demanding games on ultra settings, but there's no way to know for sure right now.

The other question I should have asked is at what resolution you want to play.  The more pixels to render, the harder a graphics card has to work.  If you're not sure, it's worth going to a store to look at various monitors; Best Buy is a good bet.  But keep in mind that as nice as a 4k monitor looks when playing videos, even a 2080 ti will have trouble running the most demanding current games in 4k at 60 frames per second.  If 1920x1080 doesn't look good enough to you, 2560x1440 is probably the right choice.

The rest of the hardware is already high quality.  The only upgrades you might consider, if you wanted, are getting a newer motherboard and a larger and/or slightly better hard drive.  The board I picked out is great, but a bit older and therefore currently $42 cheaper than its next-generation equivalent.  Either one is a great board, and there isn't currently any hardware that can take advantage of the features of the newest motherboards.  If you do want extra space on your primary hard drive, it's easy to build that in.  But it's also easy to install another hard drive later, if you ever need it, or to get someone to install it for you.  (When I say easy, this is what I mean.)

At any rate, picking out the exact components is better left for when you're ready to buy.  As an example, there's a current offer to upgrade a 512 GB solid state drive to a 1 TB version for $8, something that would normally cost around $100 on the site, depending on which brand you choose.  That sale probably won't be around three weeks from now (it wasn't two days ago), but there will almost certainly be a different useful offer instead.  Prices change so quickly, it's best to do the research, pick out what you want, and then order as soon as you see a good sale.  I'll be around whenever you're ready.
